At present, the electronic tag major part of using in staff's positioning relation system under coal mine all is the one-way type electronic tag.This electronic tag can only simply send the label of self to management system, can not send some other information (such as distress signal etc.), can not receive any information.The electronic tag that has had both enabled reception information, but power consumption is very big, and one month even once needing the replacing battery week, to make troubles to use, poor practicability does not tackle the problem at its root.
Summary of the invention
The utility model provides a kind of two-way type active electronic label of super low-power consumption, its objective is the two-way practicability that will realize active electronic label, the information indicationization, and ultralowization of power consumption solves the problem that present prior art exists.
For achieving the above object, the technical solution adopted in the utility model is: a kind of two-way type active electronic label of super low-power consumption comprises a governor circuit that mainly is made of single-chip microcomputer, wireless radio frequency circuit that is connected with governor circuit, a battery that is used for the signal lamp of display status information, a switch that is used for send state information and powers to electronic tag; Definition has an input port, this input port to lead up to first resistance to be connected with anode on the single-chip microcomputer in the described governor circuit, and switch ground connection is passed through on another road; Also defining on the single-chip microcomputer in the described governor circuit has an output port, and this output port series connection signal lamp and second resistance constitute the loop.
The related content of technique scheme is explained as follows:
1, in the such scheme, described switch is for having normally opened contact or normally closed contact.
2, in the such scheme, described signal lamp can be light emitting diode.
The utility model principle of work is: electronic tag is in park mode at ordinary times, electronic tag sends the electronic mark (id number) of self according to certain time interval, when sending after 3 times, allow electronic tag be in accepting state in the time of the 4th, wait for 200uS, if can receive data, signal lamp just carries out condition prompting according to the order that receives, if the data of not receiving, the time is overtime, and system enters in the circulation next time so.When urgent situation took place, the personnel that carry electronic tag can press the switch in the governor circuit, and system made an immediate response and entered the emission state of less radio-frequency this moment, and this state wireless transmission is gone out.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1,, thereby some status informations can be sent because the utility model has increased a switch in governor circuit.
2,, thereby can utilize the flicker of different frequency to indicate some information because the utility model has increased a signal lamp in governor circuit.
3, because the utility model adopts the MSP430F2011 single-chip microcomputer, it is low in energy consumption, battery prolongs serviceable life, and be embedded in the hardware by software programming, electronic tag is in dormant state at ordinary times, adopts timed sending, timing and the receive mode of prescribing a time limit, thereby the power consumption of greatly reducing, battery can reach more than 2 years serviceable life.
